Objective To investigate the feasibility and application scope of the looping technique by using a gooseneck snare and a loach guide wire in retrieving tubular foreign bodies within the vascular or ureteral duct. Methods During the period from July 2009 to Dec. 2013, six patients with ruptured catheter were admitted to authors’ hospital. All six patients were females. Three patients had internal ruptured peripherally inserted central venous catheter (PICC), one patient had ruptured implantable venous access port catheter and two patients had replacement of double “J” ureteral catheter stent. By using looping technique, i.e. a loach guide wire and a gooseneck snare were separately placed at the two ends of the tubular foreign body, then the gooseneck snare entangled the soft leading end of the loach guide wire to form a annular structure to seize the ruptured tubular catheter and then to pull it out of the body. Results With the help of the looping technique, the internal ruptured catheter or the double “J” ureteral catheter was successfully removed in all the six patients. Conclusion For the retrieval of the tubular foreign bodies within the vascular or ureteral duct, the looping technique by using a gooseneck snare and a loach guide wire is an effective and fast treatment. Therefore, this technique should be recommended in the clinical practice.

AIM: To study the role of NOS2 in the devel op ment of cardiac dysfunction after rat myocardial infarction by observing effects of S-methylisothiourea (SMT) on left ventricular morphology and haemodynamics. METHODS: An selective NOS2 inhibitor, was used. Administration o f SMT by gavage began 30 min before coronary ligation. Six weeks later, left ventricular morphologic and haemodynamic parameters were o bserved,and NOS2 expression, plasma NO 2-/NO 3- level and myocardial fibr osis were studied. RESULTS: Six weeks after myocardial infarction, NOS2 level in ra t non-infarct cardiac muscle, plasma NO 2-/NO 3- level, CVP and LVEDP were higher than that in controls. Long term administration of SMT decreased plasma NO 2-/NO 3- level [(26.6?6.1) ?mol/L vs (50.1?10.4) ?mol/L, P

Objective To evaluate the outcome of unconstrained shoulder arthroplasty for severe injury of proximal part of the humerus.Methods Twelve eases were all treated with unconstrained shoul- der arthroplasty.Six patients with complex fractures of proximal humerus and four with bone tumor in the proximal part of the humerus used hemiarthroplasty and two patients with osteoarthritis were managed with total shoulder arthroplasty.Cemented prostheses were used in all the cases.Results The average age was 65 years and the follow-up was 2.3 years.Two cases of complex fractures had light pain with limited external rotation of the shoulder.No pain or prosthetic stems loosening were found,and the range of motion and the function of the shoulder were satisfactory in other cases.Conclusion Unconstrained shoulder arthroplasty is a satisfactory and safe technique for severe injury of proximal humerus.

Objective To study the feasibility of using gooseneck snare combined with 0.035 inch loach guidewire for subintimal angioplasty in iliac artery occlusion , and to discuss its clinical indications. Methods During the period from October 2011 to May 2013, 3 cases with unilateral complete iliac artery occlusion were admitted to authors’ hospital. As the guidewire inserted from the healthy side could not returned into the true lumen once it entered into the subintimal space of the iliac artery , the puncture at the diseased side was carried out and the guidewire was pushed into the artery , but the catheter and the guidewire could not converge or anastomose in the subintimal site , gooseneck snare had to be used to grab the guidewire in subintimal site as to establish a path and completed the angioplasty. Results Successful and safe balloon dilatation and stent implantation were accomplished in all the 3 patients , and the patients complained of no special discomfort. Conclusion In performing the subintimal angioplasty for patients with iliac artery occlusion, the use of gooseneck snare combined with retrograde insertion of guidewire should be considered when it occurs that the guidewire can not return into the true lumen after it enters into the subintimal space. Nevertheless, gentle manipulation is first important in order to avoid the possible rupture of vessels.

Objective To investigate the pharmacodynamics of different local anesthetics administered intrathecally for elderly patients undergoing transurethral resection of the prostate (TURP). Methods Ninety ASA Ⅰ - Ⅲ elderly patients, aged 69-82 yr, with body mass index less than 30 kg/m2 , undergoing TURP under combined spinal-epidural anesthesia, were randomly divided into 3 groups ( n = 30 each): levobupivacaine group (group L), ropivacaine group (group R) and bupivacaine group (group B). Group L, R and B received intrathecai (IT) 0.5 % levobupivacaine, 0.5 % ropivacaine and 0.5 % bupivacaine respectively. The initial dose was 7,10 and 6 mg in group L, R and B respectively. The ratio of two successive doses was 0.9. If the upper sensory block reached T10 within the 20 min after IT injection, the IT analgesia was considered to be effective. The median effective dose (EDs0) and 95 % confidence interval (95 % CI) were calculated by Dixon. Results The ED50 and 95% CI of levobupivacaine, ropivacaine and bupivacaine were 6.781 (95% CI 6.561-7.024) mg, 9.135 (95%CI8.670-9.616) mg and 5.170 (95% CI 5.012-5.333) ng respectively. The relative potency ratio between levobupivacaine, ropivacaine and bupivacaine is 0.76∶0.57∶1.00. ConclusionThe relative potency ratio be tween levobupivacaine, ropivacaine and bupivacaine is 0.76∶0.57∶1.00.

Objective To assess the vitro susceptibility to 6 antimicrobial agents and genotypes of clinical isolates of Chlamydia trachomatis (Ct) from Guangzhou region. Methods Ct was isolated from clinical specimens by using McCoy cell culture and subjected to propagation. The minimum inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of 6 antimicrobial agents (clarithromycin, roxithromycin, azithromycin, doxycycline, tetracycline, ofloxacin) against Ct isolates were determined in McCoy cell culture. Nested PCR was performed to amplify the outer membrane protein 1 (omp1) VS1-2 gene followed by sequencing. Results Seventy-six Ct strains were isolated from 346 urogenital specimens, and 40 strains met the require ments for susceptibility testing after serial propagation. The MIC50/MIC90 of clarithromycin, azithromycin, roxi thromycin, doxycycline, tetracycline and ofloxacin were as follows: 0.008/0.032, 0.080/0.160, 0.125/0.500, 0.032/0.064, 0.250/0.500 and 0.500/1.000 mg/L. Seven genotypes were observed. The most prevalent geno types in decreasing order were E (14, 35%), J (10, 25%)and F (6, 15%). The MIC50 was consistent for azithromycin among the 7 genotypes, but varied by 1 - 4 folds for doxycycline, ofloxacin and roxithromycin. Conclusions Clarithromycin, doxycycline and azithromycin exhibit an excellent activity against Ct, and the activity of azithromycin is consistent among the 7 genotypes of Ct.

Through review of the major databases in English and Chinese, it is found that there is an absence of articles on special coverage of compliance of research fellows and testees in acupuncture clinical trials. Therefore, the author proposed (1) The compliance of research fellows should be guaranteed through proper work division with reasonable, standard and strict research designation as well as comprehensive systems of selection, supervision and estimation. (2) The compliance of testees should be guaranteed through enhancing of the right to know, improving of the medical environment and constructing a better doctor-patient relationship. Therefore, the compliance of clinical trials can be improved, the quality of clinical research enhanced and the reliability of the research results can be guaranteed.
